Beschreibungen/Notizen

• Projectile Coulomb excitation experiments were performed at HIE-ISOLDE at CERN with the radioactive ion beams of 140 Nd and 142 Sm. Ions with an energy of 4:62 MeV/A were impinging on a 1.45 mg/cm 2 thick 208 Pb target. The γ-rays depopulating the Coulomb-excited states were recorded by the HPGe-array MINIBALL and scattered particles were detected by a double-sided silicon strip detector. Experimental intensities were used for the determination of electromagnetic transition matrix elements. A preliminary result of the B(M1; 2 + 3 → 2 + 1 ) of 140 Nd and an upper limit for the case of 142 Sm are revealing the main fragments of the proton-neutron mixed-symmetry 2 + 1;ms states.
